So, except Survivor and ELO, best case scenario would be 11 damage (Unfuried Kolos/General Cr etc with Timber) + 13 damage (Furied Kolos/General Cr etc. with Timber) for a total of 24 damage/match which equals 24 clintz. For an average of 3 minutes per match, that would be around 480 clintz an hour times 4 hours equals 1920 clintz.
I would say that about 800-1000 clintz per day would be a more realistic scenario and a more than optimistic one so meh... not that impressed honestly.

If I understood it wrong and you can only get this bonus for one hour in that timeframe of 4 hours, then this is rubbish...
